Great weight and durabilitiy -- slips a little with chair action but protects carpet below. Simple tug once in a while brings it back into position I prefer.
I haven't had this mat for very long. About a month into using it I noticed that the plastic mat had formed indents where the casters of my chair usually sit. The casters get caught up in the indents and it has become difficult to move my chair to other parts of the mat. I'm not impressed with the mat. Oh and I weigh only 125 lbs and I have an average size office chair so I don't think I caused this problem.
This mat is the perfect size to allow me to move back & forth between two desks. Couldn't ask for anything better. Would definitely recommend it to others. Paul
This mat was purchased online in early March 2018. I made sure I got the model for 1" pile (including pad). Great shipping the mat arrived the next day.The mat does not have as the description states "Increased thickness makes for less rolling resistance." It is actually very flexible to the extent that the casters on my desk chair dent it (I weigh 155 lbs). These dents make it necessary to "rock" the chair out of them when changing positions. And this is after changing the casters to the recommended "soft" variety. Unfortunately the "lifetime warranty" is for cracks and not sags.I would seek a different manufacturer if I were purchasing this product again. The one I received is made by E. S. ROBBINS though I believe I ordered the Staples brand (as the review request indicates).
